.. MILD AND WET APRIL
THIS YEAR HAS FASHIONED EVERY MONTH MILD TO DATE, AND APRIL WAS NO
EXCEPTION WITH THE AVERAGE TEMPERATURE AGAIN FINISHING WELL ABOVE
AVERAGE. IT WAS ALSO A WET AND SOGGY START TO APRIL WITH
PRECIPITATION FOR THE MONTH WELL ABOVE NORMAL. IT WAS A QUIET MONTH
WITH NO STRONG OR SEVERE THUNDERSTORMS IN WESTERN NEW YORK. THE
SPRING WARMTH ENCOURAGED VEGETATION TO BLOOM SEVERAL WEEKS EARLY,
WITH FRUIT TREES AND SPRING FLOWERS PLENTIFUL BY THE END OF THE
MONTH.
THE TEMPERATURE AVERAGED 50.0°F FOR THE MONTH. THIS IS 4.4F DEGREES
ABOVE NORMAL, AND TIED FOR 8TH WARMEST ON APRIL RECORD. THE FIRST
FOUR MONTHS THIS YEAR HAVE ALL BEEN WELL ABOVE MONTHLY NORMAL
TEMPERATURE. WHEN COMBINED TOGETHER THEY AVERAGE 38.8°F WHICH IS THE
WARMEST START TO THE YEAR ON RECORD, TOPPING JANUARY TO APRIL OF
2012 BY A TENTH OF A DEGREE. ONE DAY AFTER THE ECLIPSE, THE
TEMPERATURE SOARED TO 78°F ON THE 9TH, THE WARMEST DAY THIS MONTH.
THE TEMPERATURE DROPPED TO 29°F ON THE 26TH WHICH IS ACTUALLY THE
MEAN DATE FOR THE LAST FREEZE FOR THE BUFFALO AIRPORT. HEAVY FROST
OCCURRED ON THE MORNINGS OF THE 25TH AND 26TH.
PRECIPITATION TOTALED 4.58 INCHES WHICH IS 13TH WETTEST ON RECORD
FOR THE MONTH. INCLUDED IN THIS PRECIPITATION WAS 0.5 INCHES OF SNOW
ON THE 4TH AND 5TH. THIS CONTINUES THE STREAK OF AT LEAST A TRACE OF
SNOW IN EVERY APRIL OF RECORD FOR BUFFALO. THERE WAS ONE DAILY
PRECIPITATION RECORD, THIS THE 1.24 INCHES OF RAIN ON THE 11TH WHICH
BROKE THE RECORD OF 1.20 INCHES SET BACK IN 1894. THE 17 DAYS WITH
MEASURABLE PRECIPITATION IS 3 DAYS MORE THAN A TYPICAL MONTH.
APRIL STARTED WITH A LARGE SYNOPTIC STORM SYSTEM THAT BROUGHT RAIN
SHOWERS ON THE 2ND AND 3RD, TO THEN BE FOLLOWED BY LIGHT SNOW ON THE
4TH AND 5TH. BRIGHT SUNNY SKIES OCCURRED ON THE 7TH, BUT WE WERE
UNABLE TO HOLD ONTO THIS SUNSHINE ON THE 8TH, WHEN MOSTLY TO
COMPLETELY CLOUDY SKIES OCCURRED DURING THE AFTERNOON OF THE
ECLIPSE. ANOTHER SYNOPTIC STORM SYSTEM ADVANCING JUST TO OUR WEST
FROM THE OHIO VALLEY BROUGHT WIDESPREAD RAIN DURING THE 11TH AND
12TH. COMBINED OVER 2 INCHES OF RAIN FELL ACROSS WESTERN NEW YORK
THESE TWO DAYS. THE WEEKEND OF THE 20TH THROUGH THE 22ND FEATURED
DRY, BUT COOL CONDITIONS. IN FACT THESE THREE COOL DAYS WERE PART OF
JUST 6 DAYS THAT AVERAGED BELOW THEIR DAILY AVERAGE. AFTER FROSTY
CONDITIONS WITH BEAUTIFUL SUNSHINE ON THE 25TH AND 26TH, WARMER AIR
FROM THE SOUTH PUSHED INTO WESTERN NEW YORK TO FINISH THE MONTH WITH
SEVERAL DAYS IN THE 70S.
THE WATER TEMPERATURE ON LAKE ERIE CONTINUED TO AVERAGE CLOSE TO OR
AT RECORD LEVELS THROUGH THE MONTH. STARTING AT 40°F THE WATER
WARMED TO 49°F AT THE MONTH'S END. WINDS AVERAGED JUST BELOW NORMAL,
AND THE STRONGEST GUST (48 MPH) OCCURRED FROM THE SOUTHWEST ON THE
12TH BEHIND A COLD FRONT PASSAGE.
IN ALL ANOTHER MILD MONTH THAT STARTED WET, BUT STILL FEATURED
SEVERAL NICE DAYS.
